This coloring page features a person wearing black boots with a small heel and a zipper up the back. The boots come up to the person's shins and give the image a sense of sophistication and style. To really make the image pop, using a variation of light and dark shades can create an interesting texture and visual depth. For example, you could use a medium-tone black for the boots, and then add a lighter charcoal for the zipper, to emphasize the detail. Adding hints of brown or red to the boots can also help to add more warmth and personality to the boots.
